Abstract

In order to solve the technical problem that a large-size aircraft assembly cannot be subjected to a rapid pressure reduction test by using an existing scheme, the invention provides a rapid pressurereduction test device and method for the large-size aircraft assembly. A rapid pressure reduction box is connected with a rapid pressure reduction box air exhaust unit, and the rapid pressure reduction box air exhaust unit can be used for reducing pressure simultaneously in the rapid pressure reduction process so as to increase the pressure reduction rate. Therefore, the rapid pressure reduction box is not limited by the maximum volume value and can be manufactured to be large, and then rapid pressure reduction can be conducted on the large-size aircraft assembly.

Description

technical field [0001] The invention relates to a rapid decompression test device and method, in particular to a test device and method capable of rapid decompression of large-sized aircraft components. Background technique [0002] Rapid decompression refers to the sudden loss of airtightness of the sealed cabin at high altitude, the pressure inside and outside the sealed cabin is quickly balanced, and the air pressure in the cabin suddenly drops, resulting in the impact of air waves. Its main hazards are: high altitude hypoxia, low temperature and low pressure. According to relevant data, in recent years, due to the loss of pressure in the cabin, many civil aviation airliners have frequently returned, made emergency landings or even crashed, resulting in immeasurable losses of personnel and property. The rapid decompression test is applicable to determine whether the rapid decompression of the surrounding environment pressure of the equipment will cause the equipment to r...
